When trying to link FreeBSD's libc compiled for mips64-unknown-freebsd I get
this linker error with ld from binutils 2.25:

This actual compiler is fairly heavily modified, but merged with trunk as of a
few weeks ago. I've found the same problems with trunk, but trunk suffers from
all the issues referenced in 23370 which prevent me from getting far enough to
get this error.
